Oxygen Atom Insertion into the Osmium–Carbon Bond via an Organometallic Oxido–Osmium(V) Intermediate

A cyclometalated osmium(III) complex, [OsIIICl(phpy)(tpy)]+ (OsIII(phpy); phpy = 2-C6H4-2′-C5H4N-κC,N) is synthesized from OsIIICl3(tpy) (tpy = 2,2′;6′,2″-terpyridine) and 2-phenylpyridine (H-phpy)...
